Sooo.. I think I found a small bug with the doombots gamemode.
I completed the first doombots level and unlocked doombots level 2.
I could play doombots level 2 and there were no problems, but now I am playing on a different computer and doombots level 2 is not unlocked. (I unlocked doombots level 2 a couple of days ago, this might be the problem instead of the computer switcheroo, not sure though)
1. Unlock doombots level 2
2. Play on a different computer (or maybe wait a few days)
3. Doombots progression is gone
Sorry for bad englisherino.
